# Ladill Link — deployment

Ladill Link is the platform URL shortener. Public short URLs live on **ladl.link**; the management app runs at **link.ladill.com**.

## Domains

| Host | Purpose |
|------|---------|
| `ladl.link` | Public short-link resolution (`/{slug}`) |
| `link.ladill.com` | SSO management UI (create/edit links) |

Both vhosts point at the same Laravel app. Set `LINK_PUBLIC_DOMAIN=ladl.link` in `.env`.

## Pricing

GHS **0.05** per link created (`LINK_PRICE_PER_LINK_GHS`). Debited from the central UserWallet via the Billing API.

## Platform onboarding

From the monolith:

```bash
php artisan ladill:onboard-app link --run-dns
php artisan ladill:launcher:sync --propagate --push
```

Register the Passport OIDC client:

```bash
php artisan passport:client \
  --name="Ladill Link" \
  --redirect_uri="https://link.ladill.com/sso/callback"
```

Set `BILLING_API_KEY_LINK` and `IDENTITY_API_KEY_LINK` on both monolith and this app.

Grant read access to platform AI settings:

```bash
sudo mysql -e "GRANT SELECT ON ladilldb.platform_settings TO 'ladill_link'@'127.0.0.1'; FLUSH PRIVILEGES;"
```

Afia reads `ai_*` keys from `platform_settings` (same as ladill.com admin). Optional `AFIA_API_KEY` in `.env` overrides for local dev.

## Legacy URLs

`https://ladill.com/q/{code}` continues to work for existing QR and storefront codes. New links use `https://ladl.link/{code}`. Unknown slugs on ladl.link fall back to the legacy resolver.

## Database

```bash
php artisan migrate --force
```

Database name: `ladill_link`.

## Country analytics (GeoIP)

Click countries are resolved from CDN headers when present (`CF-IPCountry`, etc.), then from the visitor IP using a local MaxMind GeoLite2 Country database.

1. Create a free MaxMind account and generate a license key.
2. Set in `.env`:

```env
MAXMIND_ACCOUNT_ID=
MAXMIND_LICENSE_KEY=
```

3. Download the database:

```bash
php artisan config:clear
php artisan link:geoip-update
php artisan config:cache
```

On the server, edit **`/var/www/ladill-link/shared/.env`** (not a release copy). After deploy, `current/.env` symlinks to that file. If you add env vars while config is cached, run `config:clear` before `link:geoip-update` or Laravel will not see the new values.

The file is stored at `storage/app/geoip/GeoLite2-Country.mmdb` by default. The command is scheduled weekly via the app scheduler — ensure cron runs `php artisan schedule:run` for link.ladill.com.
